Improvement in steam-generators



UNITED STATES PATENT OFFICE.

GEORGE B. BRAYION, OF PROVIDENCE, RHODE ISLAND.

IMPROVEMENT IN -STEAM-GEN ERATORS.

Specification forming part ofLctters Patent No. 44.598, dated October 11, 1864.

To all whom it may conem y Be it known that I, GEORGE B. BRAYTON, ot the city and 4county of Providence, in the State of Rhode Island, have invented certain new and useful Improvments in Steam-Generating Apparatus, which results in giving per- {ect safety from tlie dangerous and damaging etfects of explosions, thus dispensing with that constant attention heretofore rendered necessary in the production of steam, economy in the consumption of fuel, and economy in construction, as compared with the ordinary forms of steamgenerating apparatus.

rl`hese new and valuable results are obtained through a series ot' inventions fully described in this and other Letters Patent granted to me and bearing even date with this, each and all of which inventions may be used independently ot' each other, and are therefore made the subject of separate patents. Each specification is descriptive of only so much of the accompanying drawings as is necessary to understand fully the particular improvement Linder discussion; but the different specitcations, when taken in connection, make a complete description ot' the whole apparatus.

This specification has relation to one of these improvements, and is termed the heat reservoirs or suppression-plates7 in a steamgenerating apparatus, and the following is a full, clear, and exact description of the same, reference beinghad to the accompanying drawings.

In Figure 2 is shown an end view ot' the plates fm m and the position occupied by them in the apparatus. Fig. l is a side view of the same. They are made of cast-iron, in the Shape shown in the drawings, and adapted to a form of generator composed of wrought-iron pipes, which is fully described in connection with my patent for an in tercepting and transmitting medium, bearing even date with this.

g is the firespace. d are the steam-generatingl vessels. The plates m m are placed above and near the upper surface of the vessels d, leaving snfiicient space for the flames to pass between them and the vessels. Each plate extends from the center of one vessel to the center ofthe next, allowing but a small space between the different plates.

The object of the employment ot' these plates is to retard or suppress the tendency to a rapid escape of the tiames and cause the direction to be taken by them to conform to.

the shape of the upper surface of the watervessel, thus keeping the flames in contact with their whole surface and permitting` a large proportion of the heat to be taken up by the vessels before the gases finally pass up between the plates. The plates, becoming highly heated, act as heatreservoirs, and during the operation of stoking or replenishing the re they give out heat to the generating-vessels, thus serving to equalize or make up for any sudden decrease in the amount of heat given out by the tire. They can be made of castiron or other suitable material.

Having thus fully described my invention, what I claim, and desire to secure ,by Letters Patent, is

The use of plates in the furnace of a steamgenerating apparatus, substantially as and for the purpose specified.
